The objective of this study was to evaluate the effect of bump feeding for the final third of gestation on the performance of sows and their litters and on colostrum nutritional quality. Seventy hyperprolific sows of a commercial genetic line were selected according to their reproductive history. Sows were assigned to two treatments, no increase of feed (control, 2.4 kg/d of 3.25 Mcal/kg diet) or with increased feed (Bump feeding, 3.0 kg/d) from 81 days of gestation to farrowing with 35 replicates per treatment. No differences were observed for treatments on sow weight, weight gain, piglet birth weight, litter birth weight, coefficient of variation, number of total births, stillbirths, live births, and placental efficiency. The treatments also did not influence the calcium, phosphorus, ash, lactose, crude protein, zinc, ether extract, and crude energy content of the colostrum. Based on the results of the present study, the use of bump feeding in the final phase of gestation of sows becomes questionable, due the lack of effect on sow and litter performance.

这项研究的目的是评估妊娠最后三分之一的of喂对母猪及其产仔性能以及初乳营养质量的影响。根据其繁殖史选择了70头商业遗传系的高产母猪。母猪分为两种处理，从妊娠81天到分娩不增加饲料（对照，2.4 kg / d，3.25 Mcal / kg日粮）或增加饲料（颠簸，3.0 kg / d），每次处理重复35次。母猪体重，体重增加，仔猪出生体重，垫料出生体重，变异系数，总出生数，死产，活产和胎盘效率的处理未见差异。这些处理也不会影响钙，磷，灰分，乳糖，粗蛋白，锌，乙醚提取物，和初乳的粗能量含量。根据本研究的结果，由于缺乏对母猪和产仔性能的影响，在母猪妊娠的最后阶段使用凹凸不平的喂食方式值得怀疑。
